Calibrachoa plant named ‘DANOA52’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  sp. plant named ‘DANOA52’ characterized by having dark orange (closest to orange-red, RHS 30D) flowers, measuring about 2 to 3 cm in size; mounded growth habit; medium floriferous flowering habit with a long blooming season; and suitable for patios and outdoors plant beddings.

Latin name of the genus and species of the plant claimed: Calibrachoa sp.

Variety denomination: ‘DANOA52’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘DANOA52’.

Background Description of the Genus Calibrachoa

The genus Petunia was originally established in 1803 by A.L. Jussieu, who described both P. parviflora and P. nyctaginiflora as type species. Using a non-horticultural system that selected the first mentioned species as the type species (lectotype), N.L. Britton and H.A. Brown declared P. parviflora as the type species for Petunia in 1913.

During the 1980's and 1990's, H.J. Wijsman published a series of articles regarding the ancestry of P. hybrida, the Garden Petunia, and the inter-relationship of several species classified as Petunia. These studies discovered that P. hybrida and its ancestral species, P. nyctaginiflora (=P. axillaris) and P. violacea (=P. integrifolia), possessed 14 pairs of chromosomes while several other species, including P. parviflora, possessed 18 pairs of chromosomes. Since P. parviflora was the lectotype species for the Petunia genus, Wijsman and J.H. de Jong proposed transferring the 14 chromosome species to the genus Stimoryne. Horticulturists opposed reclassifying the Garden Petunia and in 1986, Wijsman proposed the alternative of making P. nyctaginiflora the lectotype species for Petunia and transferring the 18 chromosome species to another genus. The I.N.G. Committee adopted this proposal. By 1990 Wijsman had transferred several species, including P. parviflora (=C. parviflora) to Calibrachoa, originally established by Llave and Lexarza in 1825. Calibrachoa parviflora (=C. mexicana Llave & Lexarza) is now the type species for the genus Calibrachoa.

Classification of the current Petunia and Calibrachoa species is still in progress. New species are also being identified. Consequently a proper description has not been written for the Calibrachoa genus. Calibrachoa can, however, be distinguished from Petunia based on the higher chromosome number, chromosome morphology, plant branching habit and type of flower bud aestivation. Whereas Petunia species bear a flower peduncle and one new stem from a node, Calibrachoa bear a flower peduncle and three stems. Petunia species have a cochlear corolla bud, and a single outermost petal covers the other four, radially folded and terminally contorted petals. Calibrachoa flower buds are flat with all five petals linearly folded and the two lower petals forming a cover around the three other petals and fused together.

Breeding and Selection of New Cultivar

The new Calibrachoa cultivar is a product of a planned breeding program conducted by the Inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to develop a new Calibrachoa cultivar having attractive flower colors, a desirable plant habit, and a strong, vigorous growth habit.

The new Calibrachoa ‘DANOA52’ originated from a cross made in a controlled breeding program by the inventor in 2006, in Moshav Mishmar Hashiva, Israel. The female or seed parent is the Calibrachoa designated ‘CA-1466’ (unpatented) and the male or pollen parent is the Calibrachoa designated ‘CA-86’ (unpatented). The new Calibrachoa ‘DANOA52’ was discovered and selected by the inventor as a single flowering plant within the progeny of the stated cross in a controlled environment in March of 2008 in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new Calibrachoa ‘DANOA52’ by vegetative cuttings was first performed in April of 2008 in Moshav Mishmar Hashiva, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘DANOA52’ which in combination distinguish this Calibrachoa as a new and distinct cultivar:

-   -   1. Dark orange (closest to orange-red, RHS 30D) flowers,         measuring about 2 to 3 cm in size;     -   2. Mounded growth habit;     -   3. Medium floriferous flowering habit with a long blooming         season; and     -   4. Suitable for patios and outdoors plant beddings.

Plants of the new Calibrachoa ‘DANOA52’ differ from plants of the parents, Calibrachoa ‘CA-1466’ (unpatented) and Calibrachoa ‘CA-86’ (unpatented), in the characteristics described in Table 1.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new Calibrachoa ‘DANOA52’ is Calibrachoa sp. ‘DANOA36’ (patented, U.S. Plant Pat. No. 19,459), in the characteristics described in Table 2:

DETAILED BOTANICAL DESCRIPTION

The new Calibrachoa ‘DANOA52’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe plants of the new cultivar ‘DANOA52’ as grown in a greenhouse in Moshav Mishmar Hashiva, Israel, under conditions which closely approximate those generally used in commercial practice.

Plants of ‘DANOA52’ are grown outdoors in moderate climate and grown indoors during the winter. Irrigation and fertilization are needed on a regular basis. For optimal growth, grow plants of ‘DANOA52’ in full sunlight. Plants of ‘DANOA52’ are fully grown plant in 3 months when grown in full sunlight, and bloom all year-round in a moderate climate. ‘DANOA52’ is used as suitable for patios and outdoors plant beddings.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 12:00 noon in Moshav Mishmar Hashiva, Israel. The age of the plant described is 2 months.
